Use fnmatch.filter to filter files by more than one possible file extension

Question

Given the following piece of python code:

for root, dirs, files in os.walk(directory):
    for filename in fnmatch.filter(files, \'*.png\'):
        pass
         


        

Answer 1

If you only need to check extensions (i.e. no further wildcards), why don't you simply use basic string operations?

for root, dirs, files in os.walk(directory):
    for filename in files:
        if filename.endswith(('.jpg', '.jpeg', '.gif', '.png')):
            pass
